The onshore, or secondary, effects of deepwater terminal development on each of five areas selected as terminal locations. The five locations are Machias, Maine; the vicinity of Sandy Hook, New Jersey; the Delaware Bay (New Jersey); Grand Isle, Louisiana; and Freeport, Texas. The relative impacts of a terminal in each area affect the relative suitability of each area as a terminal site. Relative impacts include the additional industrial development, production employment, air and water pollution, land use, population changes, etc., resulting from terminal development. For each of the five sites studied, an economic and environmental profile as of 1970 was developed for the terminal area itself and the larger land region surrounding the terminal area. Projections were made of the economic growth of each terminal area and associated region for the years 1985 and 2000 to establish a base or reference line against which the impact of a deepwater facility might be assessed.
